Mine car loading capacity metering method based on scanning of single-line laser radar scanner

Abstract

The invention relates to a mine car loading capacity metering method based on scanning of single-line laser radar scanner. The method is characterized by comprising the following steps of: S1, vehicle information acquisition and establishment of a vehicle information database and a material information base; S2, installation of measuring equipment; S3, scanning parameter setting; S4, license plate information identification and laser radar scanning; S5, background segmentation; S6, initial material top point cloud tense correction; S7, hopper model matching; S8, square calculation of a three-dimensional model by using a slicing method; and S9, data sharing. According to the mine car loading capacity metering method, through establishment of the vehicle information database, two-dimensional point cloud data is subjected to three-dimensional processing, and three-dimensional point cloud modeling of the material is completed only by using one single-line laser radar scanner, so that the hardware cost is greatly reduced; a vehicle information system is combined with two-dimensional laser radar data, so that the loading capacity can be metered through single pass of a mine car, and the working process is greatly simplified; and a camera license plate information identification technology is combined with a laser radar technology, and metering work in an unattended state is realized.

Description

technical field [0001] The invention relates to the technical field of spatial information applications, in particular to a method for measuring the loading capacity of mining vehicles based on scanning by a single-line laser radar scanner. Background technique [0002] In recent years, with the development of mining technology, the amount of mining is increasing day by day, and the workload of mine car weighing and billing workers is heavy. Due to human reasons, there are often errors and omissions in the mining and weighing billing of mine cars, which affect mines. Mining efficiency, the existing metering method of mine car loading is difficult to meet the needs of mine development, and an intelligent mine car loading metering method is urgently needed to realize the automation of mine mining metering. [0003] Traditional weighbridge weighing is the most widely used measurement method in mine engineering construction, but it is expensive and has strict requirements for th...
